A minor point in 1444 Taungoo was a vassal to Ava until 1510 so that should be rectified
It used to be in the game, but it was taken out. Personally I approve of this change. Taungu was a tributary of Ava rather than a vassal in the "feudal" sense, and no other tributary relationships are represented as vassal relationships in game. It's consistent.
As far as I can see Mong Yang should be renamed Mong Mao as that is what the kingdom was called
No, Mong Yang (or Mohnyin, or Mèngyang) is the name of that kingdom. See e.g: A. Chan, BURMA: SHAN DOMINATION IN THE AVA PERIOD (c. AD 1310–1555).
By the time of the games start Ava was Baramised and styled itself as the decedents of the Pagans so I would recommend that they get a culture change to Burmese (Barams are a Burmese people) and Taungoo ideas get renamed to Burmese ideas and replace Avas ideas as Ava didn't have a lot in common with the shan confederacies and was largely the victim of them.
You're right that Ava saw itself as a Burmese kingdom, and as a successor to Pagan. I'd agree with changing its primary culture to Burmese even though the elite were very much integrated into Shan dynastic politics and the dynasty arguably had Shan foundations. I would not however call Ava a "victim" of the Shan states. Ava had a hegemonic relationship with the Shan, and the politics of the region were complex. One could just as easily portray the Shan conquest of Ava as an act of throwing off the Burmese yoke of domination.
Furthermore I would suggest that the requirement cores in Ava to form Shan and instead the effect of the formation gives permanent claims on Ava, the unification of the Shans should after all mean increased pains for their primary victim. (Also the shan confederacy IRL did conquer Ava)
I think it makes sense that forming Shan requires owning Ava. The original purpose of the alliance between the Shan states was to end the hegemony of Ava, so it makes sense that to truly solidify the Shan you'd need to actually conquer Ava.
Pegu and Taungoo should also start with historical friendship as often they cooperated against Ava
Pegu and Taungu also fought each other and raided one another for slaves and soldiers. One instance of co-operation doesn't negate the rest of the period's history.
Mong Mao [actually Mong Yang]-Hisenwi has historical rivalry against Ava
Fine, I suppose.
Islam spreads in Java
This is something I've tried to represent in my Indonesia mod (which I keep forgetting to update). My approach has been to try to spread Sunni Islam to provinces, and to encourage the AI to convert through a decision that requires owning Sunni provinces, as well as allowing Hindu/Buddhist states to try to combat Islamisation if they so choose.

I think these events are too heavy-handed. I'd like to see Sunda and Majapahit occasionally fall and be replaced by other nations though. I think this can be achieved more dynamically by adding cores and allowing religious disunity to do the rest.

Good idea set, though you may want to clean up the spelling errors.
